Varshavyanka submarines use which propulsion type?

• A. Nuclear-powered
• B. Diesel-electric
• C. Steam-powered
• D. Solar-powered

Answer: (B)

Diesel-electric propulsion is a common setup for conventional submarines. They use diesel engines to run on the surface or at snorkel depth to charge large onboard batteries, and when submerged they drive the propeller with electric motors powered by those batteries. Varshavyanka submarines, part of the Kilo class, are conventional (non-nuclear) submarines, so they rely on this diesel-electric arrangement rather than a nuclear reactor. This means they can operate underwater for a period, but must surface or snorkel to recharge, unlike nuclear-powered submarines that can stay submerged much longer. Steam- and solar-powered designs aren’t used for modern submarines in navies today.
